Benchmark comparison
Estimated seconds to render one frame of each standard Blender benchmark scene. Lower is faster.
These timings are derived from Blender Open Data benchmark medians and should be treated as comparative estimates, not guaranteed real-project render times.
Which GPU makes more sense?
RTX 4090 is the stronger Blender rendering pick here, and both cards have the same VRAM capacity.
Blender render speed
RTX 4090 leads by 9.8% in the Renderjuice Blender benchmark model (11,688 vs 10,642). For render-time-first decisions, that is the card to prioritize.
VRAM and scene headroom
Both cards have 24 GB of VRAM, so the decision is less about scene capacity and more about render speed, architecture, power draw, and price.
Power and cooling
RTX 4090 D is the lower-power option at 425 W TDP, compared with 450 W for RTX 4090. If render speed is close, that can make RTX 4090 D easier to cool and run quietly.
Upgrade decision
RTX 4090 D is newer, but RTX 4090 still leads this Blender benchmark comparison. That makes the older card worth considering when used pricing or VRAM capacity is favorable.
Quick take on RTX 4090 vs RTX 4090 D
RTX 4090 leads the Blender benchmark score by 9.8%.
Fastest in Blender: RTX 4090 11,687.5 score.
Lowest power draw: RTX 4090 D 425 W TDP.
Both GPUs ship with 24 GB of VRAM, so the tradeoff is more about speed, architecture, and efficiency than memory capacity.
If you are deciding between these cards for Blender, focus first on Blender benchmark score, VRAM capacity, memory bandwidth, and whether your scenes are likely to benefit more from raw speed or extra memory headroom. The comparison table above keeps those tradeoffs in one place.
